Patient Care Technician (PCT) AAH Practice Exam

What does AIVR stand for in cardiac terminology?

1. Arrhythmia Induced Ventricular Response

2. Accelerated Idioventricular Rhythm

3. Atrioventricular Interference Rhythm

4. Aneurysmal Induced Ventricular Rest

The correct answer is: Accelerated Idioventricular Rhythm

Accelerated Idioventricular Rhythm (AIVR) refers to a specific type of heart rhythm that typically occurs when the normal heart rate is interrupted or takes an unusual form. In AIVR, the heart's rhythm is faster than the usual idioventricular rhythm, often ranging between 40 and 100 beats per minute. This phenomenon can be a normal response that occurs in scenarios such as myocardial infarction, where the heart attempts to maintain an effective rate despite disturbances or blockages in the electrical conduction system. Understanding AIVR is crucial for patient care technicians, as it helps them recognize and monitor abnormal heart rhythms that could signal underlying cardiac issues. It is particularly significant in the context of cardiac care because AIVR often indicates a form of escape rhythm, allowing the heart to function more effectively during certain pathological conditions. The other options listed do not accurately reflect established terms in cardiology, emphasizing the importance of precise terminology in the medical field.
